V-COM
Virtual serial communication module IEX - RS232 / RS485
| Model number: | V-COM |
|---|---|
| Mounting: | DIN rail, 2M, 36 mm |
Applications
- Connecting field devices to cabinet ones
General description
V-COM is an IEX-2 communication module that provides virtual serial ports (RS-232 / RS-485) for Cybro controllers. It allows PLC programs to communicate with external devices through virtual COM interfaces while maintaining the same programming logic as physical ports.
The module connects to the IEX-2 bus and provides galvanically isolated communication with external serial devices.
Features
- Virtual serial port for PLC communication
- RS-232 and RS-485 interface
- Galvanic isolation between bus and communication port
- Compatible with Cybro controllers
- Multiple virtual COM ports available (COM6 – COM9)
- LED indicators for transmit and receive activity
- DIN-rail mounting

232 and 485 ports are functionally identical. Outgoing messages are transmitted on both ports, incoming messages are received from either port.
IEX-2 terminals are used when module is installed outside the distribution board, or for connecting external devices to the board.
Typical usage
Up to 4 fully independent ports
Single virtual port with multiple devices
Bus Connection Cable
- The product includes a 2.5 cm RJ9-to-RJ9 bus cable (Order code: CAD-P0) for connection to controllers, allowing the units to be linked together.
- Longer cable versions are available under order codes CAD-Px.
